摘要:Yttrium tantalate (YTaO4) nanostructures were solvothermally prepared at 240 degrees C without any additives. The quasi-square plate-like products were constructed by 50-70 nm cores and 80-100 nm nanorods with diameter of similar to 15 nm. The central part was formed by nanoparticle aggregation. The YTaO4 nanorods were formed by dissolution-recrystallization. Due to the difference of the crystal growth behavior between Y10Ta4O25 intermediate and YTaO4, the Y10Ta4O25-YTaO4 phase transformation was considered to be responsible for the formation of such exquisite structure. Nanorods grew on four perpendicular directions influenced by imperfect oriented-attachment. The luminescent and magnetic properties of as-prepared YTaO4 were investigated, which showed high luminescence quantum efficiency of 17.4% and weak ferromagnetic property. (C) 2012 Elsevier B.V.
